Abstract
A method and system for operating a hybrid vehicle that includes an integrated starter/generator and a driveline disconnect clutch is described. In one example, the method determines whether or not to rotate an engine via an electric machine while propelling a vehicle via the electric machine according to vehicle efficiency.
Claims20
A method for operating a driveline, comprising:
- ceasing to supply fuel to an engine while continuing to rotate the engine while a driver demand torque is positive in response to an electric machine torque capacity being greater than a driver demand torque plus engine friction and pumping torque of an unfueled engine.
A vehicle system, comprising:
- an internal combustion engine;
- an electric machine;
- and
- a controller including executable instructions stored in non-transitory memory that cause the controller to cut off fuel flow to the internal combustion engine in response to an electric machine torque being greater than a driver demand torque plus engine friction and pumping torque of an unfueled engine.
1 more element
A method for operating a driveline, comprising:
- ceasing to supply fuel to an engine while continuing to rotate the engine while a driver demand torque is positive in response to an electric machine torque capacity as determined from controller memory being greater than a driver demand torque plus engine friction and pumping torque of an unfueled engine as determined from a lookup table.
